Apple co-founder Steve Wozniak has criticised his own company, saying the tech giant has ruined the voice recognition app Siri.

“A lot of people say Siri. I say poo-poo. I was using it to make reservations long before Apple bought it,” said Wozniak.

The Times Union reported that Wozniak said Siri was better before Apple acquired it.

“I would say, ''Siri, what are the five largest lakes in California?'' and it would come up, one, two, three, four, five. And I would ask ''What are the prime numbers greater than 87?'' and they would come up all in a row. Then, Apple bought Siri’,” Wozniak said.

“[Now it’s], what are the largest lakes in California?'' I''d get all these lakefront properties. And I''d say ''What are the prime numbers greater than 87?'' And I''d get prime rib,” he added.

According to News.com.au, Wozniak, however, remained hopeful for the future.

"I''m really disappointed, but it''s still a market for the future,” Wozniak said.

"I think voice recognition for all the platforms is going to get better and better and better at putting together complete sentences and phrases,” he added
